Bombs Under London

Based on what I'm reading, the London bombing seem to have been nothing more than a waste of perfectly good explosives.

I don't mean to minimize the loss and suffering of the victims, but the attitude I'm hearing from London the day after the bombings is this:

We will not be terrorized by you murderous thugs.
We will honor our dead and then life will go on.
We are civilized.

We could use more of that attitude here in the States.
